问题 I've almost got this working by following the suggestions in this question Android percent screen width in RecyclerView item However that sets a height for all views, same height regardless of the content. In my case I just want to limit how tall an item inside the RecyclerView can be related to its height. In my RV I have items that have different heights, with some of those items capable of being even taller than the RV. My goal is to tell that the item can be at max 60% of the RecyclerView

问题 I want to create a chain in constraint layout that is spread but keeping the title and the text together, without a gap between them. I am trying to achieve the same view, but without the linear layout and instead a flat constraint layout: <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/scrollView3" android:layout_width=

问题 I'm having an issue to spread-chain 2 groups of elements with Constraint Layout. I understand the goal of this new layout is to use a flat hierarchy so I'd like to avoid putting my elements inside a child layouts. I looked at some awesome resources like constraintlayout.com but couldn't figure out how to make it work for my specific case - which I think can be common.. Here is an image of what I'd like to achieve. In red, spaces 1, 2 and 3 need to have the same height (just like spread chain)

问题 I have a recycler view with StaggeredGridLayoutManager. Within in I have custom items/views. Each item is defined as a ConstraintLayout where there is an image which is supposed to have a constant aspect ratio. But the image is to still be able to scale to fit the width of each span. And then the height should be adjusted according to the ratio. But somehow the images are not maintaining the aspect ratio. Here are the xml files and code to create the recycler view: item.xml <?xml version="1.0

问题 I have a toolbar like component implementation, that I'm having trouble with the layout in all situations. It has a left icon, a title and a right menu/button. I need the title to be centered on the full screen (or at least the full width of the layout) but also to not overlap with the other components. So the width of the title would have to be constrained by the left icon and the right button. I have two intermediary solutions but can't seem to find a way to combine them. One is to center
